Tensorlab is a Matlab toolbox for tensor computations, structured data fusion and complex optimization. In Tensorlab 3.0, dedicated algorithms for the decomposition in multilinear rank-(Lr,Lr,1) terms have been added. The new release introduces a tensorization framework and offers increased support for handling large-scale and structured datasets. The performance, user-friendliness and capabilities of the domain specific language for structured data fusion have been enhanced, and a new tool has been developed for the visualization of tensors of arbitrary order. An extensive new online manual has been developed. A collection of demos illustrates how Tensorlab can be used in various applications. Code, manual, demos and detailed release notes are available from the renewed website http://www.tensorlab.net/. The toolbox is free to use for non-commercial research. We hope that you will find it useful in your research. We welcome all suggestions and feedback. ------------------------------------------------------- From: Michael Heroux [log in to unmask] Date: March 31, 2016 Subject: European Trilinos User Group Meeting, Germany, Apr 2016 The 5th European Trilinos User Group Meeting (EuroTUG2016) will take place April 18-20 2016 in Garching near Munich at the Leibniz Rechenzentrum (LRZ), jointly hosted this year by LRZ and TU Munich.
